DNA SEQUENCING:
Genome of TB Culprit Deciphered

CAMBRIDGE, UNITED KINGDOM--A collaboration of European laboratories has unraveled the complete sequence of the organism responsible for one of the world's biggest scourges, tuberculosis. The sequence, announced last month, was unusually hard to decipher because of peculiarities in the TB genome. It should open new approaches to fighting the disease, which is estimated to kill 3 million people annually.
